Answer:

-6 > x

Step-by-step explanation:

3 (x-6) +2 ≥ 5x - 4

3x-18 + 2 > 5x - 4

3x - 18 > 5x - 6

-18 > 2x - 6

-12 > 2x

-6 > x

Answer:

x ≤ -6

Step-by-step explanation:

Distribute 3 through the paraentheses:

3(x - 6) + 2 ≥ 5x - 4

↓

3x - 18 + 2 ≥ 5x - 4

Calculate the sum:

3x - 18 + 2 ≥ 5x - 4

↓

3x - 16 ≥ 5x - 4

Move the variable (5x) to the left-hand side and change its sign:

3x - 16 ≥ 5x - 4

↓

3x -5x - 16 ≥ - 4

Move the constant (- 16) to the right-hand side and change its sign:

3x -5x - 16 ≥ - 4

↓

3x - 5x ≥ - 4 + 16

Collect like terms (3x and - 5x):

3x - 5x ≥ - 4 + 16

↓

-2x ≥ - 4 + 16

Calculate the sum:

-2x ≥ - 4 + 16

↓

-2x ≥ 12

Divide both sides of the inequality by -2 and flip the inequality sign:

x ≤ -6

PLEASE HELP ASAP! WILL GIVE BRAINLEIST! Find the area of the shaded region. Use pi = 3.14

Semmy [17]

Answer:

Step-by-step explanation:

Square

The side length of the square = 8 cm

The area of the square = s^2

The area of the square = 8^2 = 64

Circle

r = d/2

r = 8/2

r = 4

Area of the circle = pi r^2

Area of the circle = 3.14 * 16

Area of the circle = 50.24

Shaded Area

Area of the Shaded area = area Square - Area Circle

= 64 - 40.24

= 23.76

Forensic specialists can estimate the height of a deceased person from the lengths of the person's bones. These lengths are subs

Lera25 [3.4K]

Answer:

$130.2845\leq h\leq 137.7245$

Step-by-step explanation:

Given an inequality that relates the height h, in centimeters, of an adult female and the length f, in centimeters, of her femur by the equation

$|h - (2.47f + 54.10)| \leq 3.72$

If an adult female measures her femur as 32.25 centimeters, we can determine the possible range of her height by plugging f = 32.25cm into the modelled equation as shown:

$|h - (2.47(32.25) + 54.10)| \leq 3.72\\|h - (79.9045 + 54.10)| \leq 3.72\\|h - (134.0045)| \leq 3.72\\$

If the modulus function is positive then:

$h - 134.0045 \leq 3.72\\h \leq 3.71+134.0045\\h\leq 137.7245$

If the modulus function is negative then:

$-(h - 134.0045) \leq 3.72\\-h+134.0045 \leq 3.72\\-h\leq 3.72-134.0045\\-h\leq -130.2845\\$

multiply through by -1

$-(-h)\geq -(-130.2845)\\h\geq 130.2845\\130.2845\leq h$

combining the resulting inequalities, the estimate of the possible range of heights will be $130.2845\leq h\leq 137.7245$
